This invention belongs to the field of environmental disinfectant technology, specifically relating to a disinfectant for animal husbandry environments and its preparation method. This invention induces Bacillus subtilis fermentation through a compound extract of hawthorn, codonopsis, and astragalus. The three extracts synergistically upregulate the expression of genes related to antibacterial lipopeptide synthesis, significantly enhancing the antibacterial potency of the fermentation broth. The highly active antibacterial fermentation broth is then incorporated into a sodium alginate-xanthan gum composite gel network. Utilizing the slow oxidation properties of ascorbic acid under environmental humidity and oxygen, the gel network gradually undergoes proton dissociation, achieving a stable and long-lasting release of the antibacterial active ingredients. Simultaneously, xanthan gum swells upon contact with water to form a highly viscoelastic gel film, significantly enhancing the disinfectant's adhesion and retention capacity on humid surfaces. The resulting disinfectant possesses comprehensive properties including high antibacterial activity, long-lasting action, and strong environmental adhesion. The preparation process is simple and controllable, making it suitable for large-scale application in livestock farming environments.
